APPARATUS FOR GAS HEATING STOVES AND RADIATQRS.

Application filed May 14, 1909. a Serial No. 495,922.

To all whom it concern: I

Be it known that I, ALBERT Louis BoUoHEn, a citizen of the Republic of France, residing at Asnieres, in France, have invented certain new and useful Improvements in Apparatus for Gas Heating Stoves and Radiators, of which the following is a specification.

This invention relates to gas heating stoves, radiators and the like of the type wherein no discharge shaft is employed.

Gas heating stoves provided with a discharge shaft for the products of combustion obviously do not give out any injurious or offensive gases, but as the loss of heat car ried away by the partially consumed prodnets of combustion is large, the consumption of gas for producing a given temperature is very high, and the eficiency of the apparatus correspondingly low. Gas heating apparatus without a discharge shaft, though more efficient, give off a quantity of often sive gases and are not so safe on this account.

According to this invention a gas heating apparatus is provided in which the products of combustion, instead of escaping directly into the atmosphere or through a discharge shaft circulate in the apparatus itself, heating the walls of the casing, and returning to the burners passing through the flame and the radiating members where complete combustion takes place, the radiatng members comprising removable and in terchan eable metallic elements arranged above tie burners. This arrangement has the following advantages: Great economy, owing to the complete combustion of the ini tially, partially consumed gases, and to the recovery of the heat ordinarily carried away by them; absence of dangerous and unpleasant gases and the production of a high temerature with a small consumption of gas,

for owing to the flames being in contact with divided incandescent metal members,

the gases are burned in a more complete manner than in apparatus where the incandescent members are of fire proof material.

In the accompanying drawingsFigur'e l is a perspective view of a complete gas heated radiator accordin to this invention, some of the metallic ra diating'members being removed and a portion at the front wall being broken away. to show the burners Fig. 2 is a diagrammatic cross-section showing the path of the gases through'the apparatus.

than that shownin Figs. 1 and 2. Fig. llis a perspective view of the blank I after flanges have been formed. Fig. 5 1s a section of the gas admission valve. Fig.6 3.

a partial view of a plurality of radiating members of the form produced by blanks such as illustrated in Figs. 3 and 4:, one element being shown as partially inserted.

Fig. 7 is a cross-section of the radiating members, shown in Fig. 6, one of the elements being shown in the operative position. Fig. 8 shows a perforated blank intended to form the radiating element shown in Figs. 1 and 2. Fig. 9 is a perspective of the blank shown in Fig. 8 bent so as to constitute the element in question. Fig. 10 is a View of the whole of the radiating plate, a metallic element being also shown in the course of being erected.

The body of the apparatus comprises a double casing formed of two end plates 0 to which are connected side walls comprising two metal sheets 6, 6, between which is left an annular circulating chamber. The front portion of the walls I), b is cut away to form two rectangular openings, the. front one of which constitutes the mouthof the radiator. The rear opening is closed by removable cast iron plate 0 which engages projections of the end plates a and is provided with nickel plates or flanges d riveted there to and adapted to serve as vertical guides for removable and interchangeable metallic radiating members e mounted above the burners g of the supply pipe f which is arranged in the front lower portion of the radiator.

means of a washer is and offa screw k sccured in the plug closing the'elid of the tube.

As shown by the arrows (Fig. 2 the hot gases pass through the hollow bo of the casing and, after having heated it, return and meet the flames of the burner, which brings about a complete combustion and revents any offensive smell,'the surgoun ing airpitssin through the radiator a'fid becoming te thereby and by' -flowing through the inner space {between the outer walls of the sheet I). g

The detachable radiatin elements 6 shown in Figs. 3,4, 6 and 7 $6 designed-in the following manner :--In the' center and at the ed e ofa metal blank about 0.3 mm. thick preferably of nickel) a slot m' is formed (Fig. 3) enabling the two parts 12 and 0 thus seplaratedyto bejbent at right angles and in t e opposite directions to each other. The flat portion is subsequently cut out to form fins'or a comb along its free edge, and the teeth thus formed, which be- 'comeincandescent ,by contact with the burner flame, are bent outward away from each other as shown in Fig. 7.

.The radiating fins e} are mounted in guides formed by the nickel flanges d rivv eted side by side on the plate 0. 'Ihe flanges combustion is adm'itte 'rect, and the incompletely burned gases which have flowed through the casing of the apparatus, complete combustion of all the structe are mounted in the 'to the end ofthe burnertube f, the supply the blank and arran ed 'itscurved base. .The% folded along a generatrix, so as to form a gases being thus effected and the maximum use made of the heat so produced. Moreover, these sleeves are less fragile than the radiating fins last described In this modified construction, the radiating fins com rise a -metal blank 1' of the shape shown ig. 8,

in which are stamped out grooves s symmetrical relativelyv to the longitudinal axis of concentrically with lank is then bent and truncated cone, whereupon the superimsed, parallel edges of the blank are bent ack (as'shown in Fi 9) so as to form two projections 11 o in t e same plane and at right angles to the lane portions of the .chimne The radiatmg' members thus conguides d on the Slate c as shown in Fig'. 1.

radiating unsen burner which 1s screwed In the in t members, removably mounted within the a of gasfrom the valve is controlled by a pointed rod 72, which enables the valve to of circular shape. The result is thatit 1s possible to modify the supply of the gas without changing its pressure, as is the case withv valves provided with a transverse screw. A sleeve'q can beadjusted'on the pipe to regulate the air supply in the known manner.
